METHOD OF MAKING BUTTON-HOLE STRIPS.

SPECIFICATION forming part of Letters Patent No. 399,061, dated March 5,1889.

Application filed December 3, 1888 Serial No. 292,446. (No modeld To allwhom it may concern:

Be it known that I, HENRY \V. LYON, acitizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in theMethod of Mak- 5 iug Button-Holes; and I do hereby declare the 3following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it apperiains tomake and use the same.

My invention relates to the method of making button-hole strips, and hasfor its objectto simplify the manufacture of button-holes, and also togreatly strengthen and re-enforce the button-hole strip itself; and withthese ends in view my invention consists in the va- 1 rious stepsfollowed in the manufacture of} said strips, such as will be hereinafterfully set forth, and then specifically designated by the claims.

in the accompanying drawings, Figure l is a plan of the blank from whichmy buttonhole strip is formed; Fig. 2, a plan showing said blankpartially folded to constitute the strip; Fig. 3, a bottom view of thecompleted strip; Fig. l, a central longitudinal section of said strip,the flaps of one button-hole being shown in position preparatory tofolding; Fig. i 5, a top view of the completed strip prepara l tory tobinding; and Fig. 6, a similar view showin the side edges of the stripbound with tape, one end of the strip being turned up and sectioned.

Similar letters denote like parts in the several figures.

in the blank shown at Fig. 1 the long cuts 1 and shortcuts 2 formT-heads 3, which when folded and manipulated, as presently set forth,constitute the flaps of the button-holes throughout the strip. TheseT-heads are formed at the sides of the strip l, each head 3 being foldedupon itself, so as to form a twoply flap, as is clearly shown in Fig. 2.

5 are the button-hole slits, which are cut. 1 within the central sectionof the strip in align- 1 ment with the various cross series of shortcuts 2. After the flaps have been formed by folding the T-heads 3 uponthemselves the sides of the strip are folded inward upon the centralsection of said strip, and the said T- headed flaps are passed throughthe slits i The manner of passing the flaps i-hroughi the slits asfollows: After folding the sides of the strip inward it will be seenthat the necks of the lower flaps are immediately above the slits, whilethe necks of the upper flaps are coincident with the necks of the lowerflaps, and that the upper and lower flaps (3X- tend in oppositedirections. It will be clearly seen, therefore, that the formation ofthe button-hole is readily effected by inserting the two flaps insuccession th rough the slits, then folding them in opposite directionsagainst the strip, and finally stitching said flaps to the strip, all ofwhich is fully shown in Figs. 2, 3, =1, and 5.

In order that the button-holes maybe firmly barred at the ends, I bindthe latter on both sides with strips 6 of tape; but this barring formsno part of my present invention, since it is a well-known way ofsecuring the ends of a seriesof button-holes in a strip.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The method of making button'holes in a strip, the same consisting incutting buttonhole slits at suitable distances throughout the centralsection of the strip, forming T- headed flaps at the sides of the strip,folding said iiaps upon themselves, folding the sides of the stripinward, inserting said flaps in pairs through the slits, and folding theflaps backward in opposite directions against the strip, substantiallyas set forth.

2. The method of makingbutton-holes,which consists in forming a singleblank having button-hole slits at proper intervals within the centralsection of said blank and T-headed flaps within the'opposite sides ofsaid blank, doubling said flaps upon themselves and fold ing the sidesof the blank inward, inserting the liaps through said slits and foldingsaid flaps backward in opposite directions against 9 the blank,stitching the flaps to the blank, and finally barring the opposite endsof the button-holes, substantially as shown and set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY W. LYON.
